The Mau Rākau Shoulder (MARS) study

05 December 2024

A feasibility study to investigate the effects of Mau rākau exercises among people 55 years and over with shoulder osteoarthritis

HOW TO APPLY
Project summary


Mau rākau (long staff) is a traditional Māori mahi ā tinana (physical activity) and ancient fighting art. Mau rākau practitioners utilise a range of physical skills including active movement of the shoulder, elbow, and wrist joints. Practitioners who have achieved a high level of fluency within the artform also possess excellent upper limb mobility.

To learn Mau rākau, an individual is required to physically develop a range of motor skills and muscle strength, including movement and mobilisation of the shoulder, elbow, and wrist joints. Currently, the wānanga (learning) based practice of Mau rākau is associated mainly with cultural and social connection and, the formation of strong positive identities that positively impact the practitioner’s mental and social well-being.

But the physical health outcomes, specific to shoulder rehabilitation and functionality, have not been investigated by health researchers internationally or in New Zealand.

In New Zealand, exercise therapy interventions for GHOA are provided mainly in a clinical setting and treatments are delivered on a one-on-one basis, where a patient interacts with a health care provider individually.

Alternatively, when treatment is delivered in a community setting as an interactive group session, it provides physical activity and social interaction between participants. Participation in community exercise interventions improves exercise compliance, contributes to social and mental well-being, and reduces treatment drop-out rate.

Therefore, delivering a community exercise intervention based on Mau rākau to individuals diagnosed with GHOA may improve their holistic health and specifically improve their shoulder ROM and muscle strength, thereby contributing to the maintenance of their upper limb functionality.

Aims


Therefore, the primary aim of this study is to investigate if an 8-week programme of Mau rākau is feasible concerning adherence to exercise and dropout rate in individuals with primary GHOA. The secondary aim of this study is to assess shoulder pain responses before and after each exercise session. Lastly the study aims to evaluate the changes to the shoulder range of motion, muscle strength, self-reported shoulder function and self-reported quality of life scores after participation in the 8-week programme.

Study design and approval


The study will be a single group uncontrolled unblinded pre-post feasibility study.

The study has been approved by the Kaiārahi Rangahau Māori at the University of Canterbury. The study has been approved by the Ngai Tahu Consultation and Engagement group.
